Investment Priorities for 2017 will focus on organic growth, and in particular on:

Pre-Commercialisation for RBP-6000.

Accelerating growth in treatment of opioid use disorder in the U.S.

Pre-Commercialisation for RBP-7000.

Pre-Commercial infrastructure in China following submission of the NDA for SUBOXONE® (buprenorphine and naloxone) Sublingual Tablet (CIII) in late 2016.

Following the previously announced <$35m additional investment in 2016 in pre-commercialisation activities primarily for RBP-6000, most of which is being incurred in SD&A, we expect to increase our investment in pre-commercialisation in 2017. The quantum of additional investment for 2017 will be confirmed in February, but such cost increases will be offset in part by our previously announced cost optimisation initiative both in respect of indirect costs and in contained cost inflation on the base business.

Commenting on the key messages of the day, Shaun Thaxter, CEO, said: –

“Indivior PLC is focused on empowering patients and striving to improve their quality of life by pioneering innovative, high-quality, accessible and cost effective treatments.”

“Our performance in 2016 has run well ahead of our plan. As with last year, this outperformance against our original planning assumptions allows us to reinvest in the long-term organic growth drivers of our business.”

“Accordingly we are consciously stepping up our investment in driving long-term growth opportunities for the business. At a time when there is intensified focus by the U.S. government and regulators to address the public health epidemic of opioid abuse, addiction and overdose, it is an appropriate time to accelerate our investment and dedicate additional resources towards expanding treatment access. At the same time, we recognize that many patients and physicians continue to face unmet treatment needs. We believe that RBP-6000 buprenorphine monthly depot can potentially transform the treatment of opioid use disorder, if approved, by possibly reducing patients’ treatment administration days. Additionally, RBP-6000 was designed to offer physicians the potential for increased certainty of treatment adherence, and developed with the desire to help mitigate abuse, misuse and diversion of medication. Early investment in pre-commercialisation educational initiatives related to need for diagnosis and treatment of Opioid Use Disorder will help ensure that appropriate patients have access to this potentially transformational treatment as soon as possible, once approved. These investments will help drive long-term value for shareholders and ensure that we are well prepared for a successful launch and the best possible start in the market considering an approval is possible as soon as end 2017, assuming an accelerated review.”

IndicationSUBOXONE® (buprenorphine and naloxone) Sublingual Film (CIII) is a prescription medicine indicated for treatment of opioid dependence and should be used as part of a complete treatment plan to include counseling and psychosocial support.

Treatment should be initiated under the direction of physicians qualified under the Drug Addiction Treatment Act.

IMPORTANT SAFETY INFORMATION

Do not take SUBOXONE Film if you are allergic to buprenorphine or naloxone as serious negative effects, including anaphylactic shock, have been reported.

SUBOXONE Film can be abused in a manner similar to other opioids, legal or illicit.

SUBOXONE Film contains buprenorphine, an opioid that can cause physical dependence with chronic use. Physical dependence is not the same as addiction. Your doctor can tell you more about the difference between physical dependence and drug addiction. Do not stop taking SUBOXONE Film suddenly without talking to your doctor. You could become sick with uncomfortable withdrawal symptoms because your body has become used to this medicine.

SUBOXONE Film can cause serious life-threatening breathing problems, overdose and death, particularly when taken by the intravenous (IV) route in combination with benzodiazepines or other medications that act on the nervous system (i.e., sedatives, tranquilizers, or alcohol). It is extremely dangerous to take nonprescribed benzodiazepines or other medications that act on the nervous system while taking SUBOXONE Film.

You should not drink alcohol while taking SUBOXONE Film, as this can lead to loss of consciousness or even death.

Death has been reported in those who are not opioid dependent.

Your doctor may monitor liver function before and during treatment.

SUBOXONE Film is not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. However, SUBOXONE Film may be used with caution for maintenance treatment in patients with moderate hepatic impairment who have initiated treatment on a buprenorphine product without naloxone.

Keep SUBOXONE Film out of the sight and reach of children. Accidental or deliberate ingestion of SUBOXONE Film by a child can cause severe breathing problems and death.

Do not take SUBOXONE Film before the effects of other opioids (eg, heroin, hydrocodone, methadone, morphine, oxycodone) have subsided as you may experience withdrawal symptoms.

Before taking SUBOXONE Film, tell your doctor if you are pregnant or plan to become pregnant. If you are pregnant or become pregnant while taking SUBOXONE Film, alert your doctor immediately and you should report it using the contact information provided below.*

Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy, whether that use is medically-authorized or illicit. Unlike opioid withdrawal syndrome in adults, NOWS may be life-threatening if not recognized and treated in the neonate. Healthcare professionals should observe newborns for signs of NOWS and manage accordingly.

Before taking SUBOXONE Film, talk to your doctor if you are breastfeeding or plan to breastfeed your baby. The active ingredients of SUBOXONE Film can pass into your breast milk. You and your doctor should consider the development and health benefits of breastfeeding along with your clinical need for SUBOXONE Film and should also consider any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition.

Do not drive, operate heavy machinery, or perform any other dangerous activities until you know how SUBOXONE Film affects you. Buprenorphine in SUBOXONE Film can cause drowsiness and slow reaction times during dose-adjustment periods.
